[Bug 26131] New: dsound/duplex tests show an uninitialized variable under valgrind

http://bugs.winehq.org/show_bug.cgi?id=26131

           Summary: dsound/duplex tests show an uninitialized variable
                    under valgrind
           Product: Wine
           Version: 1.3.13
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Keywords: download, source, testcase
          Severity: normal
          Priority: P2
         Component: directx-dsound
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: austinenglish(a)gmail.com


Conditional jump or move depends on uninitialised value(s)

  Uninitialised value was created by a stack allocation
    at  CreateMMAP (dscapture.c:460)

though perhaps that's an alsa bug?

Are your sure ?

since pdbi->mmap is already assigned before calling CreateMMAP()

    This->mmap = mmap;

    snd_pcm_prepare(This->pcm);
    CreateMMAP(This);

The bug is actually mmap_mode 

   mmap_mode = snd_pcm_type(pcm);

    if (mmap_mode == SND_PCM_TYPE_HW)
        TRACE("mmap'd buffer is a direct hardware buffer.\n");
    else if (mmap_mode == SND_PCM_TYPE_DMIX)
        TRACE("mmap'd buffer is an ALSA dmix buffer\n");
    else
        TRACE("mmap'd buffer is an ALSA type %d buffer\n", mmap_mode);


since mmap_mode is not related to access_mmap (e.g. pulse does not support mmap
but the trace still say

"trace:dsalsa:CreateMMAP mmap'd buffer is an ALSA type 28 buffer"

type 28 is SND_PCM_TYPE_IOPLUG ( it can be jack or pulse plugin )


    err = snd_pcm_hw_params_set_access (pcm, hw_params,
SND_PCM_ACCESS_MMAP_INTERLEAVED);
    if (err < 0)
    {
        err = snd_pcm_hw_params_set_access (pcm, hw_params,
SND_PCM_ACCESS_RW_INTERLEAVED);
        if (err < 0) { WARN("Could not set access\n"); goto err; }
        mmap = 0;
    }
    else
        mmap = 1;
